BACKGROUND

The expanded buffer material, such as Expandable Polyethylene (EPE or Expanded polypropylene (EPP), is the most used material for the shipping package of liquid crystal panel currently. The packaging scheme is basically applying the sealed package. Namely, each layer of boxes is closely stacked up serially, and the whole stack is wrapped with wrapping films and then covered with the waterproof film of Polyethylene (PE). However, when the products are transported to the destination by a container and are unpacked, the water mist or the water drops are frequently found generated inside the wrapping films and inside the boxes.

Regarding the above issue, the current general solution is to dispose desiccants around the packaging boxes. Though the desiccant has a certain of water absorption effect, it can only absorb the water around the liquid crystal panel, and cannot absorb the water on the surfaces of the liquid crystal panel. Besides, for reducing the impact force among the liquid crystal panel, the buffer materials would be disposed among the liquid crystal panel. The buffer materials are generally the low water absorption of materials, so the water mist on the liquid crystal panel would be kept all the time and cannot be absorbed by the desiccants.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The specific structural and functional details disclosed herein are only representative and are intended for describing exemplary embodiments of the disclosure. However, the disclosure can be embodied in many forms of substitution, and should not be interpreted as merely limited to the embodiments described herein.

Referring to FIG. 1, in this embodiment, the spacing pad with water absorption function for liquid crystal panel comprises a first buffer layer 20, a second buffer layer 30 and a water absorption layer 10. The first buffer layer 30 and the second buffer layer 30 are disposed opposite to each other. The water absorption layer 10 is disposed between the first buffer layer 20 and the second buffer layer 30. The first buffer layer 20 is formed with multiple first water absorption holes 21 thereon, and the second buffer layer 30 is formed with multiple second water absorption holes 31 thereon. The multiple first water absorption holes 21 and the multiple second water absorption holes 31 are both applied for exposing the water absorption layer 10. When the spacing pad is interposed between two liquid crystal panel, the water on the surfaces of the two liquid crystal panel would be entering the water absorption layer 10 through the multiple first water absorption holes 21 and the multiple second water absorption holes 31 separately, to guarantee the whole surfaces of the liquid crystal panel being dry.

As a preferred embodiment, the first buffer layer 20 and the second buffer layer 30 are made of expandable polyethylene (EPE). This kind of material with good buffer performance can reduce effectively the impact force among the liquid crystal panel and prevent the liquid crystal panel from breaking. Surely, in other embodiments, the first buffer layer 20 and the second buffer layer 30 can be made of expanded polypropylene (EPP). The water absorption layer 10 is made of the high water-absorbent resin material. The high water-absorbent resin material with good water absorption and high water-retention would not release absorbed water when the water absorption layer is extruded. Besides, the high water-absorbent resin material has good elasticity after absorbing water, so during the transport of the liquid crystal panel the water absorption layer 10 can still provide a certain of buffer effect.

In specific, an inner sidewall of the first water absorption hole 21 is inclined, and an angle between the inner sidewall of the first water absorption hole 21 and a bottom of the first water absorption hole 21 is an obtuse angle. Namely, the first water absorption hole 21 is a tapered hole, and the diameter of one end of the first water absorption hole 21 far away the water absorption layer 10 is larger than the diameter of the other end of the first water absorption hole 21 close to the water absorption layer 10. Thus, the inner sidewall of the first water absorption hole 21 has a certain of slope to have the water on the surfaces of the liquid crystal panel flow easily into the water absorption layer 10. The larger opening end of the first water absorption hole 21 is attached to the liquid crystal panel for contacting larger area of the liquid crystal panel, thereby beneficial for absorbing more water and further guaranteeing the whole structure stability of the spacing pad.

Further, for guaranteeing both two sides of the spacing pad have good water absorption, an inner sidewall of the second water absorption hole 31 is inclined correspondingly, and an angle between the inner sidewall of the second water absorption hole 31 and a bottom of the second water absorption hole 31 is an obtuse angle. Namely, the second water absorption hole 31 is a tapered hole, and the diameter of one end of the second water absorption hole 31 far away the water absorption layer 10 is larger than the diameter of the other end of the second water absorption hole 31 close to the water absorption layer 10. As a preferred embodiment, each one of the multiple first water absorption holes 21 is facing the corresponding one of the multiple second water absorption holes 31. It should be explained, the inclined angles of the inner sidewalls of the first water absorption hole 21 and the second water absorption hole 31 can be set artificially.

In specific, as shown in FIG. 3, the cross-sectional shape of the first water absorption hole 21 and/or the second water absorption hole 31 along the direction parallel to the water absorption layer 10 is preferably a circle. Surely in other embodiments, as shown in FIG. 2, the cross-sectional shape can also be, but not limited to, a hexagon, and can be other polygon shapes or honeycomb shape.

Further, the multiple first water absorption holes 21 and the multiple second water absorption holes 31 are separately arranged in multiple columns and multiple rows, for guaranteeing the contact parts, between the first water absorption hole 21 and the liquid crystal panel, or between the second water absorption hole 31 and the liquid crystal panel, are distributed evenly, thereby beneficial for the water absorption layer 10 absorbing completely the water on the liquid crystal panel.

In other embodiments, as shown in FIG. 4, the first water absorption holes 21 are long bar shaped holes extending along the width direction of the first buffer layer 20, and the multiple first water absorption holes 21 are arranged at a fixed interval to each other along the length direction of the first buffer layer 20. Correspondingly, the second water absorption holes 31 are long bar shaped holes extending along the width direction of the second buffer layer 30, and the multiple second water absorption holes 31 are arranged at a fixed interval to each other along the length direction of the second buffer layer 30. Thus, the contact areas, between the first water absorption holes 21 and the liquid crystal panel, and between the second water absorption holes 31 and the liquid crystal panel, are individually increased, thereby beneficial for absorbing more water.

As shown in FIG. 5, the difference between the spacing pad with water absorption function for liquid crystal panel in this embodiment and the spacing pad in the first embodiment is that the multiple first water absorption holes 21 and the multiple second water absorption hole 31 are staggered mutually. Namely, the projections of the first water absorption holes 21 on the water absorption layer 10 and the projections of the second water absorption hole 31 on the water absorption layer 10 are not overlapped, so the water flowing through the first water absorption holes 21 and the second water absorption holes 31 are absorbed by different parts of the water absorption layer 10,thereby beneficial for the water diffusion in the water absorption layer 10 to promote the water absorption of the water absorption layer 10.

The present invention provides a spacing pad with water absorption function for liquid crystal panel. The first buffer layer, the water absorption layer and the second buffer layer are arranged in a stacked structure, and the first buffer layer and the second buffer layer are made with water absorption holes thereon, for providing the spacing pad with buffer effect and at the same time being able to absorb the water on the liquid crystal panel.
